在飞行试验中,在对窄脉冲信号采集记录时,由于采样率高,导致数据量大,事后数据处理分析效率低。本文针对此问题,提出了一种采集记录的优化方法。本方法对窄脉冲信号进行高采样率采集,对每个采集数据进行判决,对符合判决条件的数据进行时间标记并记录。最后,经过地面恢复,得到全时域的窄脉冲信息。经过软件仿真,验证该方法有效。本方法在可接受的信息损失的条件下,对数据量进行了优化,提高了硬件利用率及数据处理分析的效率。
In the flight test, when collecting and recording the narrow pulse signal, the data amount is large due to the high sampling rate, and the data processing analysis is inefficient afterwards. In this paper, aiming at this problem, an optimization method of acquisition record is proposed. In the method, the narrow pulse signal is sampled at a high sampling rate, the judgment is made on each collected data, and the data meeting the judgment conditions is time-stamped and recorded. Finally, after the ground is restored, narrow-pulse information in the full-time domain is obtained. After software simulation, verify that the method is effective. Under the condition of acceptable information loss, this method optimizes the amount of data and improves the efficiency of hardware utilization and data processing and analysis.
